Question

the rectangle below has an area of x^2-6x-7, square meters and a width of x-7 meters.What expression represents the length of the rectangle?

Answer 1

Length = (x^2-6x-7)m²/ (x-7)m

Explanation:

let L =length

let W= width

let A = area of the rectangle.

if A = L × W

making L the subject, divide both side by W

A/W= L×W/W

therefore, L =A/W

L= (x²-6x-7)m²/(x-7)m
